lie it known that I, RALPH Siiimux, a Citizen of the United States,residing at Sunlun v, in the county oi Northninlwrland, and State ofPennsylvania, have invented eertain new and useful Improvements in Speedand Running Iiuie indicators, of 'lliPli the following aSPQClfitlltlOIl.

In my prior patents, lie-is. H.196 and No. 1,022,801. I have shown aninstrument for registering the running! time of a Vehicle,- that is, thetime he veLii-le is in autnal operation or motion during any given tripor period of time. as; well athe speed at any time that the machine inoperation. The running time feature of the instruinont is very desirablefor enabling; the owners of trnrks and il ll\'l" \'flg keep advised asto the hours of btl tfl, of each individual machine. and also as to thehours that the employ are, artoalh engzaizjrdinoperatingitheni nine.'lliue.

The instrument referred iii will. however, ehon' thatthe maehine ha nern in actual operation lor only half an hour, and[ix-nee that the employee has made a long atop during the trip and hasrarer! the \ahi. e to make up for the lost time. I

The invention tit the pres nt aimlhfatinn embodies the running timeteatnro of the prior patents referred to, together with means Forregistering the diatanoe traveled by the vehicle when driven in exeeqsof a given speed, and means for .'-ignalirg r the driver when hisvehicle in traveling at a speed in (,Xt'tSF of Such given speed.

The invention is pai'tieularl denil'ahlo on trucks and delii'ervveliirles which are, not intended for high speeds and which are in--jurionsly ail'eeted when driven fast.

This isaccomplished by means fully described in my prior Patent No. 1,022,801,and unnecessary to describe in detail. here, these auxiliary drivingdevices comprising a spring pressed lever 52, mounted upon the lever 29,and carrying a spring pressed pawl 53 which engages a ratchet wheel 54,the latter being rotatable with the clutch member 41, associated withthe clock train. 7

The shaft 38, which is'actuated by the clocli train, rotates once in twominutes. Upon the upper end of this shaft is mounted a worm gear 55which engaged by a spur gear 56 upon a shaft 57, mounted in the bracket'2' and upon this shaft is arranged a. worm which engages agear 59 upona shaft (50 which leads to and operates the register 7 for reg steringthe total running time of the vehicle. Another worm 61 is mounted upon.the shaft 57 and this worm engages a gear 62 upon a shaft or spindle(53, to which the indicating hand 6 is attached, and this hand indicatesupon the scale 5 the runing'time of the vehicle for any given trip, orthe trip-hours.

Upon the spindles'Q'T and 63 are mounted heart-shaped cams FA and 65 anda reset ting slide (:6 is suitably formed and arranged to actuate thesecams and thereby turn the indicator hands 4 and (3 to zero on thescales, when the slide is operated. It is unnecessary to describe indetail the construction and operation of thisslide as equivalent meansfor re-settiug indicator hands is well known in the art.

The main feature of the present invention is the means For indicatin andregistering distance llI-l'x'Qlk'll at speeds in excess of a given speedwhich will now be described.

llpou the upper supporting plate 14 of the instrunu-nt are arrangedguides (37 and on, having slots to receive a slide (39, th slot in theguide (38 being considerably wider than the slid-J to permit latcralmovement of the slide. The slide is provided with a. Stop '70 adapted toabut against the. guide (37, and the lo is normally held with the stopagainst saulguide by a spring 71 attached to the guide and to an arm 72,cured to the slide. This spring is at an any to the enter line of theSlide and therefore tends to hold the end portion m of the slide againstthe end portion 68" of the guide (38. he end portion (19" ot' the slide,which may be termed the. forward end portion, projects over the wormwheel 16 and into the path of movement oi two top 0f the guide 68.

pets 73 which are arranged at diametrically opposite points on saidwheel. The center line of the slide is radial to the axis of the wheel16 and the end of the slide which is adapted to be engaged by thetappets is beveled in opposite directions from the center, as shown at(39, to provide cam-sub faces so that each time a tappet passes the endof the slide, the latter will be moved rearwardly by the tappet and itwill then be drawn forwardly by the spring 71 to its normal position.Each time the vehicle moves a given distance, say one-sixtieth of amile, this backward and forward move ment of the slide takes place. Theslide has, on its under side, a roller 74 which normally rests againstone side of a pawl 75, pivoted to the plate 14, and the free end of thispawl projects into the path of movement or" a shoulder 76 upon a disk76, which latter is secured to the clutch member 3 of the time mechanismby a sleeve 76 surrounding the shaft 38. Hence, when the ve-.

hicle is in motion, the disk 76 and its shoulder 76 will rotate in thedirection of the arrow with the clutch member 34, and with the timemechanism, while the main spring is pulling the said mechanism and thisdisk, and this shoulder will be rc-set in an initial position each timethe clutch member 34 is reset in its initial position at the completionof eachunit of distancev traveled by the vehicle. l/Vhen the shoulder 76is moved to its initial. position, it'moves the 'pawl or movable guide75, which, in turn, bearing against the roller 74 on the Slide, movesthe slide away from the end 68 V Thi'slateral movement of the slide bythe time controlled shoulder 76 occurs about the time the slide hasreaclied its rearward limit of movement. The slide carries a dog, 77pivoted to the slide at 78 and adapted to engage one arm 79 of a bellcrank lever 79 when the slide is held a sullicient distance away fromthe end (38 of the slot in the guide-68, during the backward travel ofthe slide. The arm 79 of the bell crank lever is connected by a link 80to a crank arm 81 connected to the register 9. A suitable spring 82holds the arm 79" of the bell crank-lever normally in pdsition to heengaged by the dog 77 when the slide is held a sufficient distanceqaway31 travels down the radial surface 28 of one of the cams on the camwheel 28, and lhe clutch member 34 and disk 7G.are-re-set in theirinitial positicfi'is, the shoulder 76f on the disk moving the rear end.of the slide laterall so as to car'ry the spring pawl or dog 77 outbeyond the projecting arm 79 of the bell crank lever. The slide thenmoves forward, the pawl 77 slipping past the arm 79 and at thecommencement of this forward movement, the time controlled shoulder 76*commences to move with the time mechanism and to allow slide 9 to swingtoward the end (58 of the slot 68. If the movement of the vehicle is inexcess of a given speed for which the partsare set, say twenty miles anhour, the slide will move forward and will he pushed rearward again byone of the tappets before the shoulder 76 has been carried far enougharound by the time mechanism to allow the pawl 77 on the guide 69 tomove out ol the path of the arm 79 on the bell crank lever, and hence,the pawl will engage said'arm during the rearward movement of the slide,causing the. arm to rock and operate the register 9. If, however, thevehicle is moving at a rate lower than the predetermined limit of twentymiles, the shoulder 76" will move far enough from its initial positionduring the forward and back movement of the slide to allow the latter tocarry the pawl 77 out of line with the arm 75%, and hence the pawl willpass the arm without causing an operation of the register 9. From thisit will be evident that whenever the. vehicle exceeds a predeterminedspeed, the register 5) will operate to record the distance traveled atits excess speed, and so lon as the vehicle travels at less than thisprer etermined speed, the register 9 will not be operated.

In order that the pawl 75, which is used simply as a guide for theroller 74 on the under side of the slide, may not press on the shoulder7l'i af tier tlie latter has started to move with the time mechanism,the guide 75 may be connected by a pin and slotted link 86 to an arm 29on the lever 29. As this lever rocks when the time mechanism is re-setand then is slowly moved by the cam wheel 28, the link may be used tosupport the guide 75 during a part of the movement of the slide afterthe time mechanism has moved a certain distance from its initialposition.

In the figures above described, only one excess-speed register is shown;but I may employ several to register distance traveled at differentexcess speeds as illustrated in Figs. 5 to 7, inclusive. In Fig. 5, themechanism is substantially the same as in Fig. 2, except that the pawl77 in Fig. 2 is arranged to engage a. single hell crank, while in Fig. 5the pawl 77 which is mounted upon and travels with the slide (30, has aforked end adapted to engage bell cranks for operating two registers, 9and 9 The forked ends 77 and 77 of the pawl, at low speeds, travel inpaths at one side of the arm 79" of the bell crank 79 and straddle aprojection 9O on an arm 90 of a bell crank 90. The bell crank 79operates :the register 9 and the bell crank 90, through a, link 91operates the register 9. Another bell crank 92 is mounted upon a stud 93which supports all of the bell cranks and the bell crank9'2 has one arm92, somewhat longer than the arm 79 of the hell crank 79 and shorterthan the arm 90 of the bell crank 90. This bell crank '92 has an arm 92to which is attached a pin 9i, fitting into a slotted arm 95 of a signalplate 95 which is pivoted upon a suitable post 96. This signal is hiddenby the casing when in the position shown in Fig. 5, but when the bellcrank 92 is rocked, one part marked 15 in the drawing will show throughan opening 97 in the casing. and when the bell crank is rockedfurtliier, another part of the signalplate, marked 20 will show throughsaid opening.

It has previously .beenexplained in con nection with Figs. 14, and Figs.8!), inclusive, that the longitudinal movement of the slide 69 iscontrolled by the speed of the vehicle, while its lateral swingingmovement, toward the axis of the disk '76, is controlled by the timemechanism. To repeat, briefly, the spring 71 constantly tends to movethe slide forward, or longitudinally, toward the axis of the gear 16, onwhich the tappets 73 are mounted, and also to swing the slide laterallytoward the axis of the disk 7 6, its rear end having room to play in aslot in the guide. 68, as shown in F ig. 8?, and being normally pulledby its spring toward the side 68 of said slot. \Vhen the slide, moved byone of the tap' pets 73, is in. its reairmost position, the clutchmember 34, and the disk 76, which is secured to said memher, are turnedbackward on the time mechanism by the operation of the cam disk 28, andin this resetting movement,

which occurs at fixed distances of travel bf the machine, the shoulder76 of the disk 76, swings the slide away from the axis of said disk. Theslide is then moved forward by its spring and again moved rearward by asucceeding tappet, and during this forward and backward movement theslide slowly swings laterally toward the axis of 1 0 varies according tothe speed of the vehicle,

it is evident that if the speed is great? the pawl 7 7 which is mountedon the slide, will move rearwardly'therewith in a path farther from theaxis of. the disk 76 than if the speed is slow, and that it will followintermediate paths at intermediate speeds. To set up on the register 9the distance traveled at speeds of fifteen miles and not over twentymiles per hour, and on the register 9 the distance traveled at speeds oftwenty or more miles per hour, without registering speeds under fifteenmiles perhour, the arms 00 and of the bell cranks which operate theregisters will be of such lengths and so related to the paths ofmovement of the pawl 77 'on the slide 6 that when the \e hicle is movingat a. speed below fifteen miles per hour, the pawl will not engageeither bell crank, and neither register will be operated. When moving atfifteen miles, the pawl will engage in its rearward movement the bellcrank 90 but not the hell crank 70. and when the vehicle is moving attwenty miles or over, the pawl will engage, in its rearward movement,the bell crank 7 but not the bell crank 00. \Vhen the vehicle is movingat any speed below fifteen miles per hour, the pawl will not engage thearm 92, and when moving at fifteen miles or over, the pawl will engagethe latter arm and cause the' movement of the signal 95.

In Fig. 6, the forks 77" and 77 of the pawl are shown in the positionwhich they occupy relatively to the bell cranks at a speed below fifteenmiles per hour. At these low speeds, it will be noted that the forks ofthe pawl straddle the downward projection 90 on the arm 90, and both ofsaid forks are at the left of the bell crank and 92 and therefore noneof the bell cranks will be operated in this position of: the pawl. Atfifteen miles per hour, and less than twenty miles, the forks of the awlwill travel in a path to the right of that indicated in Fig. 6, so thatthe fork 77" will engage the downward projection 9O on the arm 90 andoperate the register 9. The fork 77 will, at the same time, engage theend of the arm 92 and this will cause the signal 95 tohe swung up so asto expose the numeral 15 thereon through the opening 97. At thisspeed,however, the fork 77" will pass the end of the arm 7 9 and the register9 will not be operated. Upon increase in speed to twenty miles or moreper hour, the fork will travel in a path farther to the right in Fig. 0,andthe arm 77 will then engage the bell crank 79 and operate theregister 9, and it will also engage the arm 92 and move the signal 95 toexpose the numeral 20 through the opening 97; but in this last assumedposition of the pawl, the fork 77 thereof will travel in a path at thefight of the projection 90 on the arm 90, and the latter will thereforenot he moved, and hence, the register 9? will not be operated. 'Thesignal, when operated, serves the purpose of calling the driversattention to the fact that he is runningat a speed above his limit.

In order to keep the signal plate in front of the opening 79 as long asthe speed is excessive, a locking pawl 100 is pivoted upon a stud 101 onthe supporting plate 1%, and this pawl is spring pressed toward a segment 102. which is connected to the signal plate and is provided withnotches 103 and nu for engagement with the locking pawl. A tripping rod105, connected to an arm of this pawl, extends through an opening in theguide piece (37, into the path of the tappets 73 on the wheel 10. If thesignal plate has been thrown up to expose the numeral 15 through theopening 97, the pawl 100 engages the notch 103 and the signal plate istherebly held with the numeral 15 exposed through the opening. If thespeed continues at fifteen miles an hour, the engagement of one of thetappets 73 with the reeds twenty miles per hour, the bell cranks 79 and92 will be simultaneously operated, as before explained, and thesignal-plate will be thrown up to expose the number 20 through theopening 97 by the opera- .tion of the bell crank 92, and the pawl 100will engage the notch 104, in. the disk 102, and lock the signal platein position-With the numeral 20 exposed through the opening 07. Thiswill not be pchanged as long as the speed equals'or exceeds twenty milesper hour, as at such speeds the bell crank 92 will always be engaged bythe forked arm 77 at the moment when the tripping arm 105 is operated,and when this arm is released, the pawl 100 will still be in engagementwith the notch 104. If the speed now falls below twenty miles and notbelow fifteen, the arm 77 of the pawl 77 will engage the low part of thebell crank 92, and when the tripping arm or rod 105 is operated the pawl100 will be released from the notch 104, and the signal plate will dropand said pawl will engage the notch 103 and hold theslide with thenumeral 15 exposed through the opening 97. But if the speed drops belowfifteen miles per hour, the forked pawl will not engage any of the' bellcranks and at the next operation of the tripping rod 105, the pawl100will be re leased from the notches in the disk 102 and the signal platewill drop below the opening 97. L

.- In Figs. 10 and 11, I have shown a centrifugally operated indicatorfor indicating and registering distance traveled at excess speeds. Inthese views the shaft 105 is driven by a speed proportional to the speedof the vehicle and carries a centrifugal governor 106 which operates topull downward a sleeve 107 on the shaft 105, against the action of a.spring 108, as the speed increases. A gear 109 upon this sleeve isadapted to engage a gear 110 upon a register 111 when the speed equals agiven limit, as say fifteen miles per hour. These gears Will remain inmesh as long as the speed of the vehicle continues at fifteen miles perhour, or any speed above fifteen and less than twenty miles per hour.Should the Vehicle speed equal or exceed twenty miles per hour, anothergear 112 on the sleeve 107 will be brought into mesh with a gear 113upon a register 114, and the latter will register the distance traveledat a speed of twenty miles per hour or at any greater speed. The teethon the. gear 113 are long enough to permit the gear 112, after its firstengagement, to remain in mesh therewith, while the latter gear iscarried to its downward limit of movement by the operation of thegovernor, so that for all speeds above twenty miles per hoiir, the gear112 will drive the gear 113 and operate the register 114. It will beevident that as the speed drops below twenty miles per hour, the sleevewill move upward, carrying the gear 112 out of engagement with the gear113, and carrying the gear 109 into engagement with the gear 110, andthe register 111 will be operated by the gears 109 and 110 until thespeed drops below fifteen miles per hour, when the gear 109 will passout of engage ment with the gear 110, and below a speed of fifteen milesper hour, neither of the registers will be operated. A signal plate orarm 115 is pivoted to the casing at 116 and has an arm 115 which extendsbetween collars 117 on the sleeve 107, the arrangement being such thatwhen the vehicle is operating at speeds varying from fifteen to twentymiles per hour, the signal arm will i be rocked into position to exposethe numeral 15 thereon through the opening 118 in the front wall 119 ofthe casing, and if the speed equals or exceeds twenty miles per hour,the numeral 20 will be exposed through said opening. If the speed is below fifteen miles per hour, the signal arm will remain below the openingin the casing. A distance register or odometer 120 is sh own in thelower part of the casing, ano it is connected by gears 121 and 122 tothe shaft 105, this register being continually operatcd while thevehicle is in motion to register the total distance traveled.
